i just got my hands on 3 fabulous 120mm Papst fans ... the real ones, that would be : fully made of metal, a helluva lot CFM -> the industrial version of those plastic thingies we are used to

but, there is a minor side to these beauties : they run at 220V, so that would mean integrating some way to hook them up directly to the powernet (dnno how it's said in english, don't feel like looking it up or poundering about it ...)

i know, it ain't hard ... and i could perfectly do this, but i'd rather not ...

does anybody now any way to convert this to 12V, so i can hook em up to my regular psu -- or is this against all rules of electronix or something ?
